SDIC Bioenergy (Jidong) Co., Ltd. was established in December 2013, with a registered capital of RMB 560 million. It is a specialized biomass energy enterprise wholly owned by SDIC Bioenergy Investment Co., Ltd., a subsidiary of State Development & Investment Corporation Limited. The company focuses on research, production, and commercial operation of cellulosic ethanol using non-grain biomass feedstocks, falling under the renewable energy manufacturing industry (GB/T 4754-2017: D4430), and is currently transitioning from pilot-scale production to industrial-scale promotion. Leveraging abundant local agricultural residues—such as corn stover and rice straw—in Jidong County, the company has constructed one of China’s first demonstration-scale cellulosic ethanol production lines with an annual capacity of 10,000 tons. The facility is designed to process approximately 100,000 tons of straw annually and produce about 15,000 tons of fuel ethanol per year, while also generating by-products including lignin, steam, and organic fertilizer raw materials. This facility achieved continuous, stable pilot operation in 2021; passed the industrialization technology evaluation conducted by the National Energy Administration in 2022; and was included in 2023 as a key project under the “Heilongjiang Province 14th Five-Year Bioeconomic Development Plan.” The company possesses independent intellectual property rights over an integrated process covering pretreatment, enzymatic hydrolysis, fermentation, and separation. Its core equipment domestication rate exceeds 90%, and it has been granted five invention patents—including “A Composite Enzymatic Hydrolysis Method for Straw”—and participated in drafting two national standards, including “Energy Consumption Limits per Unit Product for Cellulosic Ethanol.” Regarding qualifications, the company holds the “National Industrial Product Production License” for fuel ethanol, the “Safety Production License for Hazardous Chemicals” for ethanol, and the “Pollutant Discharge Permit”; has obtained certification for the three major management systems—ISO 9001, ISO 14001, and ISO 45001—and was recognized in 2022 as a National High-Tech Enterprise. Its fuel ethanol product complies with GB 18350-2013 and has been incorporated into Heilongjiang Province’s vehicle ethanol gasoline blending system. Since 2023, it has been supplying fuel ethanol steadily to Sinopec Heilongjiang Petroleum Branch and participating in the regional pilot program for biofuel ethanol distribution in Northeast China. Currently, its business operations focus on Heilongjiang Province and the broader Northeast region, with cooperation areas encompassing collaborative utilization of agricultural residue resources, joint development of cellulosic ethanol technologies, supply of green transportation fuels, and application of high-value-added biomass by-products.
